2.5 Gbps wired home network



Much cheaper than 10Gbps network as you can use CAT5e, and there are cheap PCIE adapter for desktop and USB 3 adapter (Type A or Type C) adapter for laptop/desktop.

The switch is more expensive though.

For desktop adapter, the cheapest TP-Link 2.5Gbps adapter is only at RMB89 or S$18 from Taobao.

Why do you need a router here? For internet access, 1Gbps is good enough and Singapore's 2Gbps is fake one (more like 2*1Gbps or 2Gbps distributed to 4 ports and each port caps at 1Gbps).

So we are talking about internal home network now, where a 2.5Gbps dumb switch will do, no need expensive routers.

BTW, Asus RT-AX86U and RT-AX11000 do have a 2.5Gbps LAN/WAN port. But the WAN port is useless in Singapore context. The LAN port might be useful.

Anyway, I just placed an order for one Ugreen Type C to 2.5Gbps adapter and one Ugreen USB 3 to 2.5Gbps adapter through Taobao. They will probably arrive in 3 weeks through 3rd party sea shipping.

nice.. perfect for mini atx/nuc with pcie slot to try make a soft router (i wonder how much cpu routing 2.5gbps needs...)

If just for a few devices, even a Pentium G4440T is said to be okay for 10Gbps (2 ports 10Gbps plus 4 ports 1Gbps), 2.5Gbps should have lower requirement.

Another one with Xeon 2678 v3.

The performance may not be as good as the Mikrotik 10G switch as per the articles.

No idea about what you are talking about. You are mixing up WAN side and LAN side.

Whether you are using ONR or ONT, and no matter which ISP or which internet plan (be it 500Mbps or 1Gbps, 2Gbps or 10Gbps), you can have a sub network with 10Gbps or 5Gbps or 2.5Gbps within the home network.

Read the thread here about 10Gbps home network as well.
